Unreal Engine Blueprints have been a game-changer for me personally, no pun intended. The rapid prototyping, API discoverability, and total immunity to 99% of dumb syntax errors which drag-and-drop visual programming provides has been a great help to learning Unreal. At the end of the day my ambitions are bigger than what I can efficiently build with Blueprints, but they're a great starting point for demos and small one-off applications.
